\ application filed March 2,. 1912. Serial nb. seiner.

Be itkno tat i, 11 i-LLMER A. EKHOLM, a citizen of the United States,residing at Marmarth. in the county of Billings, State of North Dakota,have invented certain new and useful Improvements in Railway-Ties; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to, which it appertains to inalievide a tie of this character withmetal reintorcing members, the same being applied during the moldingprocess, and being arranged so as to impart extra strength to the tie,and to prevent any undue vibration of the same.

With these and other objects in view, the invention consists in certainnovel features of cmistruction, combinatimi and arrange ment of parts aswill be hereinafter fully de scribed and claimed.

In the drawing: Figure .l is a perspective view of the tie, the samebeing shown in dotted lines and the reinforcing members, rails and thesecuring means therefor being shown in full line. Fig. 2 on line 2-2 ofFig. 1. Fig. is a similar view on line 3 2 ot'l ig. 1. Fig. at is atragmentary top plan view of a portion of the tie. Fig. 5 is aperspective view of the tie.-

Rcterring to the drawing, the numeral 1 designates a tie, the same beingformed from cement or the like, and is substantially rectangular inshape. The side edges of the central portion of the tie arc beveledinwardly, as indicated at 2, while the rcmaiuing portion of the tie isrectangular in cross section. Embedded in the tie t are a plurality ofreinforcing members 23, the ends of which stop at a point short of theends of the tie and are provided at their centers with arches 4 whichassume a position near the upper central surface of the tie. 'lhereinforcing members 4 are arranged in spaced parallel relationthroughout; their length, the number of which may be varied as desired.A substantially Ushapcd reint'orcing rod 5 is employed, the same. beingembedded in the lie 1 and is positioned near is a sectional view thelower surface thereof, the legs 6 of which have their upper endsprojected slightly above the upper surface of the tie, and are benttoward each other to form hooks 7 for engaging the outer flanges of therails 8, said hooks being projected from the tie a shor u distance fromthe ends thereof. Passing through the central portion of the tie 1 are apair ot reinforcing rods 9, the same being also substantially Ll-shaped,and have their leg portions 10 threaded at the upper ends and projectedslightly above the upper surface of said tie. Rail attaching plates 11are provided, and are formed with beveled outer edges 12 for engagingthe inner flanges of the rails 8, said plates having a pair ofperforations 13 for receiving the threaded ends of the legs 10 of therods 9. clitlllplllg nuts 1-1 are placed upon the threaded ends or" thelegs 10, and may be manipulated to either firmly clamp the plates 11 inposition to hold the rails 8 securely, or may be adjusted to release theplates when it is desired to remove a rail or rails.

By providing the tie 1 with the inwardly beveled side edges as shown at2, the same is prevented from becoming center bound the weight beingequally distributed near the ends of the tie, thus reducing vibrationtoa minimum. The beveled side edges of the tie will readily take intothe road ballast, and it e angular faces 15 produced therel will preventlateral movement of the tie. l1; will be noted from this constructionthat he rods .7 and .9 are arranged in tying relation of the arches oithe rods 3, thereby greatly strengthening the tie at its centralportion.

llhat is claimed is:

A railway tie comprising a plastic body in which are embedded aplurality of metal rods extending longitudinally from end to end withinthe body with their intermediate portions arched and their end portionsin a common plane parallel with the upper face of the body and a seriesor additional metal rods extending longitudinally within the body andalter-mating with the first named rods and extending beyond the archesof the latter, the last named rods including a middle rod having i endportions extended vertically beyond the arches with i.s extremitiesturned toward each other and a rod at each side of the middle rod havingIn testimony whereof, I afiix my signaits endh portilons egtefidingupwardly beture, in presence of two Witnesses.
